Use Star Wars Force Unleashed 2 profile for the crappy Fable 3 game to force AA.

Thanx, works like a charm!

Btw, when I forced AA via Radeonpro after making the SWTFU2-profile it didn't take any affect, but the CF-part did as the framerates doubled.
I had to set AA in CCC and now it's playbale with the mighty supersampling

No I don't think so, I have tried a lot of them and its the same performance. The game seems pretty CPU limited from what I can tell. SLI scaling on Nvidia cards isn't good either from what people have posted on the forum.
